Deciding what is significant and what is not is often a concern to tribunal members.
When we see the injury that could be caused by imports from China in this context, we accept that this injury is much less significant in order to apply the measure. On the other hand, in the case of a normal safeguard measure, this must be the principal cause of the injury.
I know that this is not specific or mathematical, but given the tribunal's experience, we distinguish between the most significant reasons and a reason.
